Neuromodulation in Post-stroke Aphasia Treatment
AbstractPurpose of ReviewThis paper aims to review non-invasive brain stimulation (NIBS) methods to augment speech and language therapy (SLT) for patients with post-stroke aphasia.Recent FindingsIn the past 5 years, there have been more than 30 published studies assessing the effect of transcranial direct current stimulation (tDCS) and transcranial magnetic stimulation (TMS) for improving aphasia in people who have had a stroke. Different approaches to NIBS treatment have been used in post-stroke aphas ia treatment including different stimulation locations, stimulation intensity, number of treatment sessions, outcome measures, type of aphasia treatment, and time post-stroke.SummaryThis review of NIBS for post-stroke aphasia shows that both tDCS and TMS can be beneficial for improving speech and language outcomes for patients with stroke. Prior to translating NIBS to clinical practice, further studies are needed to determine optimal tDCS and TMS parameters as well as the mechanisms underlying tDCS and TMS treatment outcomes.
Discussion Memory is an important part of what distinguishes higher order species from others. Memory also is part of one’s self-identity. Difficulties in short-term memory can make common, everyday tasks difficult for the person experiencing the problem particularly if it recently occurred and the person’s long-term memory is intact. Difficulties with long-term memory can also have problems when language, events or even one’s own identity are affected. For some people the memory loss is temporary but for others, memory impairments are permanent and must be accepted and accommodated as part of the overall...
CONCLUSIONS: This is the first observation of SD occurring after cSDH evacuation. SD occurred at a rate of 15% and was associated with neurological deterioration. This may represent a novel mechanism for otherwise unexplained fluctuating neurological deficit after cSDH evacuation. This could provide a new therapeutic target, and SD-targeted therapies should be evaluated in prospective clinical trials. PMID: 32217801 [PubMed - as supplied by publisher]

Abstract Aphasic discourse has been investigated through two major approaches: a micro-linguistic approach and a macro one, but the separate analysis of the micro and macro aspects of aphasic discourse has led to a noticeable gap between them. Cohesion analysis is one of the possible ways that can directly connect these two aspects. However, few studies have investigated cohesion in aphasic discourse in an integrated manner. The present study employs a mixed-methods approach to examine whether and how patients with fluent and non-fluent stroke-induced aphasia differ from normal individuals in the cohesion of their...

Conclusions The WIM and the MATTR are promising measures that quantify lexical diversity in different and complementary ways. The WIM may be more useful for quantifying the effect of treatment or disease progression, whereas the MATTR may be more useful for discriminating discourse produced by people with very mild aphasia from discourse produced by neurotypical controls. Further validation is required. PMID: 32191154 [PubMed - as supplied by publisher]
Aphasia is one of the most severe symptoms in stroke patients, affecting one-third of acute stroke patients. We aimed to investigate the prevalence and outcomes of aphasia in patients with acute ischemic stroke (AIS).
